INSPECTION PROCEDURE 4: AWD system check screen is displayed on the center of the multi-information display and a "AWD" symbol flashes at the left top. But no diagnostic trouble codes are set.
COMMENTS ON TROUBLE SYMPTOM
- When a AWD system check screen is displayed on the center of the multi-information display and a "AWD" symbol flashes at the left top without setting any diagnostic trouble codes, the power supply to the AWC-ECU may be defective.
- When the power supply voltage to the AWC-ECU drops under approx. 6 V, the ECU cannot set any diagnostic trouble codes due to the poor power supply. In this case, the combination meter will determine that the AWC-ECU is timed out, and then display "AWD system check" at the center of the multi-information display and make "AWD" symbol flash at the left top.
PROBABLE CAUSES
- Damaged wiring harness and connectors
- Malfunction of AWC-ECU
DIAGNOSIS
1. Check the Inspection Procedure 5: Malfunction of power supply circuit system (Refer to 
). 2. Check the trouble symptom.
